Claims

[Claims for Utility Model Registration] 1. A speaker system in which a closed tube with a length of one-fourth the wavelength of the bass frequency to be reproduced is attached to a speaker, and a slit is provided near the speaker attachment part of the closed tube. 2. A speaker system in which a closed tube with a length that is an odd number multiple of the quarter wavelength of the bass frequency to be reproduced is attached to the speaker, and a slit is provided near the speaker attachment part of the closed tube. 3. A speaker system in which a closed tube with a length of 1/4 wavelength of the bass frequency to be reproduced and a closed tube with a length of 1/12 wavelength are attached to the front and rear of the speaker, and a slit is provided near the speaker attachment part of the closed tube. 4 Attach a closed tube with a length of 1/4 wavelength of the bass frequency to be reproduced to the speaker, provide a slit near the speaker attachment part of the closed tube, and add 1/6 wavelength of the bass frequency to be reproduced on the opposite side of the closed tube. A speaker system with an open tube of length.
